W'ATER MOTOR.

Application filed August 20, i924. Serial No. 733,055.

This inventionl is a water motor and the obj ect of the invention is to provide a novel and eiiicient power unit adapted to be hydraulically operated from a faucet.

The invention embodies numerousl novel Y v section of the'casing features. For example, the water motor ernployed as a power unit is reversible and comprises two rotors 'against either of which water from a faucet may be directed in such manner that the stream impinging the blades of the rotor will do so under maximum velocity and thus effect the generation of lmaximumV power. This stream moreover may be directed by the employment of novel mechanism into cooperation with either one of the said rotors to the exclusion of the other depending upon the direction in which it is desired to 'rotate the driven shaft with which said rotors are associated.

v 'A further novel feature .resides in the particular manner of associating and supporting the water motor on the faucet in such manner as to preclude leakage.

Other novel features and advantages are inherent in the motor construction and collectively render it compact, economical and durable, as well as highly efficient in the performance of its functions. 1

These features will bev apparent from the hereinafter detailed description and claims when read in conjunction with the accompanying drawings.

The accompanying drawings illustrate'on'e practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure Figure 3; Y

Referring to the drawings, 1 designates a motor casing which, in accordance with this invention, is struck up from sheet metal by means of suitable dies. The casing is made in two parts or sections 2 and 3 of slightly different size, so that the section 2 can telescope into the section 3 to form collectively a closed casing in which the rotor or rotors are positioned for operation. On the upper 4 is a section on the line 4-4 of part of the sections 2 and 3 are formed substantially seinicylindrical neck sections 4 and 5,. respectively, and at the bottom of these sections 'are correspondingly formed outlet sections 6 and 7 so that when the parts are telescoped together the sections 4 and 5 and the sections 6 and v7 cooperate to form a substantially cylindrical inlet and a substantially cylindrical outlet. Intermediate the ends of the sections 4 and 5 is formed an annular groove or channel 8 and above this channel said sections are longitudinally corrugated as shown at 9. 'Within the channel A 8 a water switching member 1() is mounted to Arotate and is operable manually by means of a `finger piece 11 rigid with the member 10 and` extending radially through segmental slots 12, as shown in Figure 4, A rubber bushing or sleeve 13 extends into the corrugated portion ofthe water inlet and a spring 14 is coiled about the bushing, so as to liebetween the bushing and the metallic neck to compress the rubber bushing in an inward radial direction and adapt it to better grip a `faucet over which the bushing is adapted to be slipped.

The bushing 18 is provided at its upper end with va turned over flange 15, which extends over the upper edge of the inlet neck and gives a finished appearance thereto, and at the same time. precludes undesirable shifting of the bushing downwardly intothe neck. The bushing, however, is made sufficiently long so that its lower end will at all times press against the upper surface of the member 10 and form a gasket therewith to preclude leakage of the water from the time the water leaves the faucet until it passes through the water switching member 10. Y In the drawings, the faucet is designated by the reference character 16 and it will appear especially from Figure 2 that when the pump casing is associated with the faucet in the manner described a water tight connection will be established for the passage of the water from the faucet through the water switching member 10. The body of the casing 1 is substantially cylindrical andtheV opposite walls of said body are perforated to provide seats for bushings 17 and 18 .in which a shaft or spindle 19 is mounted to revolve. l

Positioned within the casing and fixed for rotation on the shaft or spindle, preferably by virtue of a tight forced lit are two rotors 2O and 21. These rotors are provided with blades 22 and 213, respectively positioned to be operable from opposite directions, as clearly shown in Figure 2. Between the rotors 2O and 2l is positioned a spacing or dividing disk 24 of substantially the same diameter as the two rotors and all of these parts are ef substantially the same inner diameter as the casing but allow sufficient clearance to provide unrestricted rotation of the rotors in either direction.

The water switching member l() is formed with a flange Q5 at its upper edge, which flange finds bearing in the annular channel 8 in the inlet neck and below the flange 25 the member l0 is in the form of a twisted funnel being shaped to direct'y the water leaving said member in such direction that it will properly impinge the blades of either rotor depending upon the direction in which it is desired to drive the shaft 19. The outlet of the passage leading through the switching member is designated 26 in Figure el and when in the position shown in Figures 2, 3 and 4 will direct the stream against the blades Q3 of the rotor 21 to drive the shaft 19 in a counterclockwise direction. If, however, thc finger piece l1 is shifted from the full line position in Figure 4 te the dotted line position in Figure 4, the outlet QG will be moved to direct the stream into engagement with the blades 22. Both sets of blades are scooped so as to properly entrain the stream and derive maximum e iiciency from the velocity of the water. In this manner, the direction of rot-ation of the shaft may be readily controlled by simply manipulating the finger piece 1l to direct the stream into cooperation with either rotor.

Attention is here directed to the fact that the construction described is such as to secure maximum velocity of the water leaving the switching member and there is no backing up of the water from the time it leaves the switching member until the time it impinges the blades and thus I obtain maximum efficiency in driving power. Moreover, the passage through the switching member is such as to produce maximum impetus of the flow. These features are important since if the water is backed up to any appreciable extent or its fiow impeded, el'iicieney will be lest and the driving power of the suction will be appreeiably ef- 'feeted Experience has shown, however, that in the construction illustrated, relatively high power is obtained and the shaft 19 is driven in a positive and steady manner. It is also to be noted that the particular shaping of the blades is such as to leave practical negligible periods of shut ofi' and the stream will cooperate with one blade and imping4 the same in substantiallj7 perpendicular direction until it engages with the next blade.

Another important feature of the inven tion, as thus far described, resides in the fact that practically all the metal parts which have been referred to may be struck p from sheet metal at a relatively small cost and the parts may be accurately manipulated in dies, so that they will properly lit when assembled. This enables me to market the device at a low figure, much lo ver in fact than has heretofore been possible for a water motor t' this character.

The water after acting upon the blades gravitates in a spent condition into the lower portion of the cas whence it flows hrough the outlet neck and in accordance with this invention, the water leaving the outlet neck does not splash in the sink as heretofore, but is directed to a flexible tube 2T directly into the waste pipe of the sink or basin. To enable me to cifect this result, one end of a rubber tube 2T is slipped over the outlet neck, while the other end of said tube is fitted over a metal liner Q9 of a rubber stopper 30. A wire holder 3l. may be associated with the tube and liner as shown in Figure l, so as to tightly bind these parts together. rPhe stopper 30 is of a size to fit the outlet of the sink and when positioned therein the water leaving the niotor casing will be discharged directly into waste pipe 28.

In Figure l, a fragment of the sink is shown at 32 and from this figure the operation of the device will be apparent.

Connected to one end of the shaft 'lil in any suitable manner is a flexible driving connection 33, which may be of any conventional form. As shown iu the dra vings, however, it embodies a casing?r or envelope 3i having a coiled wire core 35, one end of which encircles one end of the shaft l!) and is firmly aflixcd thereto and the other end of which is similarly secured to a chuck member (not shown). The envelope extends the full length of the connection and is of any suitable construction which will render it flexible. At the end of the connection adjacent the motor, the joint between the shaft end and the connection is preferably enclosed within a thimble or sleeve 3T which, in practice, can have a forced fit or be otherwise secured to the bushing 17, while the opposite end of "he connection 33 is enclosed within a hand piece 3S of any suitable material, but preferably metallic.
